Abstract

A method for use by a code division multiple access (CDMA) cellular base station having a first and a second antenna, the method comprising transmitting first synchronization information from the first antenna during a first time slot, a duration of said transmission of said first synchronization information being less than a duration of the first time slot; and transmitting second synchronization information from the second antenna during a second time slot, a duration of said transmission of said second synchronization information being less than a duration of the second time slot.
